A New Approach for the Generation and Reaction of Organotin Hydrides: The Development of Reactions Catalytic in Tin.

A New Approach for the Generation and Reaction of Organotin Hydrides: The Development of Reactions Catalytic in Tin.Page 342.The first experimental paragraph in the Supporting Information should read as follows. Generation of Bu 3 SnH from Bu 3 SnCl, Aqueous KF, and Polymethylhydrosiloxane (PMHS).A solution of Bu 3 SnCl (12.00 g, 10.00 mL, 36.87 mmol), aqueous KF (4.71 g, 81.10 mmol; 3 mL H 2 O), and PMHS (2.43 mL, 40.56 mmol) in THF (30 mL) was stirred at room temperature until the initially formed Bu 3 SnF precipitate disappeared (∼3.5 h).An aqueous solution of NaOH (3 M, 20 mL) wad added, and the reaction mixture was stirred overnight.The organic phase was separated, washed with saturated NH 4 Cl solution, water, and brine, and then dried over MgSO 4 .Evaporation of the solvent gave 10.65 g (99%) of Bu 3 SnH, which contained 2-3 mol % of PMHS by 1 H NMR. Vacuum distillation (0.25 mmHg, 70 °C) of this material yielded 8.80 g (82%) of analytically pure Bu 3 SnH as a colorless liquid.
